TIRE-SETTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 600,117, dated March 1,1898. Application filed July 5, 1994.. Serial No. 516,52I-l. (No model.)

To all whom it may concern:

Be it known that I, MILTON G. BROOKS, a citizen of the United States ofAmerica, residing at Longton, in the county of Elk and State of Kansas,have invented certain new and useful Improvements in Tire-Settin gMachines, of which the following is a specification, reference being hadtherein to the accompanying drawings, and the letters of referencethereon, forming'a' part of this specification, in which Figure 1 is aside elevation of thetire-setter represented with the rim of a wheelplaced therein as when in service. Fig. 2 is a top view thereof showingthe wheel in section. Fig. 3 is a similar View, omitting the wheel andwheel-clamping device and having a portion of the tire-grippingkeysremoved. Fig. 4 is a vertical longitudinal section of the portion of themachine and a side view of the sliding head thereof. Fig. 5 is an endelevation of the machine. Fig. 6 is a vertical cross-section of the sameadjacent the center thereof. Fig. 7 is a detailed view of a pair of thetirez 5 gripping keys of the machine. Fig. 8 is a detailed perspectiveof the wedge-plate for adjusting the seat of said keys, and Fig. 9 is adetailed side View of the cross-eccentric of the machine.

3o This invention relates to certain improvements in a hand-operatingmachine or device for setting wagon-tires without removing the tire fromthe wheel; and it consists of certain construction and arrangement ofparts,

3 5 which improvements are fully set forth and explained in thefollowing specification and pointed out in the claims.

Referrin g to the drawings, B represents the body or body-frame of themachine, having formed therewith feet 13" for securing it to a floor orbench, as shown at A in Fig. 1, by means of bolts V, as shown. Saidbody-frame is further provided with one end portion raised and shaped toform a horizontally-curved surface, Gr (see Fig. 3,) withcorrespondinglycurved sides a Ct, thus forming what I have termed thefixed head of the machine; also, said body-frame is provided with thehorizontal benches E, one at either side, upon which is placed thesliding head B, which has a dependinglongitudinal cross-head K, whichhead, and said sliding head is provided with one of said brackets J,arranged to operate between said brackets J, which brackets are of acommon surface plane with that of said heads, as shown in Figs. 3 and 4,and for the purpose of providing a support at the place between saidheads.

S is a cross-shaft placed through a crossbearing of the body-frameadjacent one end thereof, as shown in section in Fig. 4, which shaft ismade at each end with an eccentric section S and with a square sectionS, extending centrally from said eccentric, as shown' in Fig. 9, andlinks, as shown at D, are placed with one end on said eccentrics and theother end on said extending lugs R of the sliding head B, so that byrotating said crossshaft said links will be operated by said eccentricsto draw said sliding head toward said fixed head, or vice versa, and asa means of turning said shaft the wrench-levers L are employed byplacing them on said square sections S" of said shaft, as represented inFigs. 1 and 2, which are grasped by operators who 85 apply power bodilythereto to attain the desired movement. One or two of said wrenchleversmay be employed with one or two operators, as the work to be done maydemand. As a means of retaining said links D on the said eccentrics'andlugs the body-frame is provided with side extending lugs M, which haveset in them upright pins or posts T, oneadjacent the outer side of eachlink, which prevents the removal of said links prior to 5 the removal ofsaid pins T.

P and P are posts fixed in benches E, one post in each bench adjacentthe fixed head of the machine, the post P being made with an eye at itsupper end which has jointed I00 therewith the forked end of a crossclamparm 0' by means of a bolt or cross-pin G,

which clamp-arm is made with a hole through its opposite end so arrangedthat when thearm is brought to a horizontal position the upper end ofthe part P will protrude through said arm hole, and a cross-pin cl isplaced through a hole of said post above said arm end to prevent saidarm end rising at certain times; but when said pin is removed said armmay be turned up off of said post and back to clear the space betweensaid two posts P and P.

C is a cranked screw turned through a correspondingly-threaded hole inthe clamparm 0 and has swiveled on its lower end a foot-piece Z. Theface sides a and a of said heads are respectively made with theirbearings or contact-faces at an angle longitudinally of the machine, asshown, and the tiregrippingkeysF and F, which are respectively placedupon the surfaces Gand G of the machine-heads, are provided withcorrespondingly-shaped edges adapted to register with said head sides,as shown, the opposite edges of said keys being reduced in width, asshown in Figs. 5 and 6, and serrated or roughened along said edges, asrepresented in Figs. 2, 3, 4, and 7.

In setting a tire the clamp-arm O is first turned back. The wheel isthen placed jointly upon the faces,G and G of the machine-heads, whichbrings the wheel-tire between the serrated or gripping edges of the keysF and F, when said keys bybeing given a longitudinal movement ride intoward and against the tire, caused by reason of their angling bearings.The clamp-arm C is then brought over and secured over post P, and thescrew 0 turned down to bring the foot Z to bear firmly against the rimof the wheel W, after which the operating-lever L is grasped andoperated, or two of said levers may be operated jointly to draw thesliding head, as before described, which movement, by reason of theangling bearing of the said tire-gripping keys, causes said keys to bewedged and gripped hard against the edges of the tire to firmly hold, sothat continued movement causes the section of tire between the two headsto be upset, and thus shorten the circumference of the tire, henceaccomplishing what is termed setting the tire, the wood rim of the wheeland the brackets J and J of the machineheads preventing the buckling ofthe tire during such operation. WVhen a tire is thus set, a reversemovement of thelever L will reverse the head B and thereby release thegrip of the keys F and F from the edges of the tire.

The curve of surfaces G and G of the two heads of the machine is made toregister with that of the rear or larger wheels of a wagon, so that theserrated edges of the keys F and F will register evenlywith the edges ofthe wheeltire,(see the left side in Fig. 4 and dotted lines in Fig.1,)and when smaller wheels,as the front wheels of a wagon, are operatedupon to set their tires wedge-blocks or plates H are employed by placingthem under the outer ends of the said grip-keys to raise the outer endand thus change their curvature so they will more evenly grip the edgesof the tire of such small wheels, as represented at the right in Fig. 4.

Having thus described my invention, what I claim as new and useful, anddesire to secure by Letters Patent, is as follows:

1. In the tire-setting machine described, the combination with thegripping-heads thereof provided with the sides a, and a, having theirengaging faces made respectively with the two-part or double inclines,and the gripping-keys F and F, provided with the serrated or roughenedgripping parallel edges, the twopart or double inclines, respectivelyadapted to register With said inclines substantially as set forth.

2. The combination of the stationary gripping-head, provided with thedouble inclined sides, the double inclined tire-grippingkeys, andmounted on the bench-frame as shown; the sliding gripping-head providedwith corres pondingly-inclined sides, with the inclined tire-grippingkeys, the side extending lugs, and mounted on said bench-frame thecrossshaft boxed in said frame, provided with the eccentric, and thesquare lever-shank at each end, the links placed connecting said,eccentrics with said sliding-head side lugs; the lever, or levers, foroperating said eccentricshaft; and the tire and felly holding clampattached to said frame, substantially as set forth.

3. In the tire-setting machine described, the combination with thegripping-heads,provided with sides a and at, having their engaging facesmade respectively with the twopart or double inclines, the gripping-keysF and F, provided with the serrated or roughened gripping paralleledges,and with the twopart or double inclines respectively adapted toregister with said inclines, and the wedgeblock H.

4. The combination of a stationary gripping head, provided with thedouble inclined sides, the bracket J, the double inclined tire-grippingkeys mounted on the bench-frame as shown, the sliding gripping-headprovided with correspondingly inclined sides, the brackets J, theirinclined tire-gripping keys, with the side extending lugs, and mountedon said bench-frame; the wedge-block H, the cross-shaft boxed in saidframe and provided with the eccentric, and the square lever-shank ateach end, the links connecting said eccentrics with said sliding-headside lugs, the lever or levers for operating said eccentricshafts, andthe tire and felly holding clamps attached to said frames.
